A carriage for a rail-guided conveying system, in particular a gravity conveyor, in which a plurality of similar carriages are mounted one behind the other in the rail-longitudinal direction and displaceable in the rail-longitudinal direction, on a running rail extending in the rail-longitudinal direction. A first and a second set of upright rollers are arranged one behind the other for guiding the running rail in the rail-longitudinal direction and which in each case are rotatably mounted on a carriage body transversely to the rail-longitudinal direction about an associated axis and are spaced apart from one another along the associated axis.

A method and system for fulfilling customer orders having a data base that is adapted to store a plurality of customer orders and identity of warehouse inventory items and return inventory items that make up each of the customer orders. Some of the orders are single item orders with only one inventory item assigned to that order. Some of the orders are multiple item orders with multiple inventory items assigned to that order. Returned items that are processed and determined to be acceptable to be re-distributed are re-introduced into the inventory data base and are available to be assigned to an order. Warehouse inventory and return inventory are maintained independent of each other to reduce redundant operations. The order fulfilment system retrieves items from either or both of the warehouse inventory and return inventory to fulfil customer orders. The order fulfilment system may utilizes human associates or robot associates.

The invention relates to a conveying device comprising at least one movable carriage on which at least one first group and at least one second group of track rollers are disposed, and a track rail disposed so as to be locationally fixed for guiding the carriage. The track rail has at least one track face, at least one straight portion and at least one curved portion. The track rollers are configured in such a manner that during movement of the carriage along the straight portion, exclusively the track rollers of the first group roll on the track face assigned to the straight portion, and during movement of the carriage along the curved portion, exclusively the track rollers of the second group roll on the track face assigned to the curved portion. The invention furthermore relates to a further conveying device and corresponding carriages, as described herein.

A conveying apparatus for food-processing industry articles includes a conveying device to convey articles in a transport direction with holding elements adapted for receiving the articles. At least one guide extends in the transport direction, and guides guide elements arranged thereon in the transport direction. One holding element is vertically adjustably arranged on each guide element. Controllable adjusting means are arranged on the conveying line for adjusting the vertical position of the holding elements relative to the respective guide element. The adjusting means controllably come into adjusting engagement with passing holding elements to adjust the holding element vertical position. Each holding elements is arranged on the respective guide element by a self-holding device configured such that the holding element is upwardly movable relative to the guide element against gravity and is downwardly releasably locked in a stop position. An assembly for processing articles and corresponding methods are also provided.

Meat processing equipment is disclosed that includes a first element having a first face; a second element having a second face. The first and second faces extend parallel to one another and define a common plane between the first and second faces. The first and second elements are relatively movable with respect to one another. Yieldable arresting features are included for yieldably arresting the first and second elements in at least one predetermined position of relative movement, the yieldable arresting features include cooperating first and second permanent magnets, associated with at least one of the first and second elements.

A roller track includes a base, parallel guides, roller support bars placed into their respective guides, and a plurality of rollers removably disposed between the roller support bars. The roller support bars preferably are removably secured to the base via the respective guides which are affixed to the base. The base also can be provided with connecting elements sidewalls thereof such that a plurality of bases of roller tracks can be connected laterally to accommodate any width of shelf or display planogram. Thus, the roller tracks can be used either separately roller tracks or as a continuous mat (i.e. a plurality of roller tracks affixed to adjacent roller tracks). Additionally, dividers can be removably affixed to each roller track via securing members comprising an upper body portion formed via a living hinge and at least one lower connector that removably connects the securing member to the roller track.

A conveyor for suspended objects includes a first rail profile having a first upper track and a second track arranged below the first track, a conveyor chain that can be moved continuously in a direction of conveyance in the first track. The conveyor includes holding adapters for holding objects to be conveyed, with each holding adapter having a head part that is mounted so as to roll in the second track and is coupled to the conveyor chain. A sorting portion having a switch that follows in the direction of conveyance and via which the holding adapters can be transferred from the first rail profile to a second rail profile. The switch includes an overdrive and a drive belt, with the overdrive configured such that during operation the running speed of the drive belt is higher than the running speed of the conveyor chain.

A conveyor for suspended objects has a first rail profile having a first, upper track and a second track arranged below the first track, a conveyor chain having lateral friction roller pressing surfaces to drive the conveyor chain continuously in the first track. Holding adapters for conveyed objects are coupled to the conveyor chain, with the holding adapters being transferred into the first rail profile by an induct switch. A pressing piece arranged on a side of the conveyor chain opposite the drive roller is adjustable between an active and a passive position. The adjustment path of the pressing piece is dimensioned such that in the active position the conveyor chain is in contact with the drive roller and in the passive position the conveyor chain is not in contact with the drive roller, whereby in the active position the drive roller can be driven by the conveyor chain.

The invention relates to a transport carrier (2) and a transport carrier system for an overhead conveying device (1), in which the transport carrier comprises a universally applicable base body (30) and supporting body (40a, 40b) exchangeable by means of a connecting device (50), which supporting body (40a, 40b) in a first configuration is provided with a completely enclosed receiving opening for transporting transport bags, and in a second configuration is provided with a suspension hook for transporting an article suspended on a clothes hanger. The connecting device (50) comprises a profile groove (60) extending perpendicular to the longitudinal axis (51) and a profile projection (61) extending perpendicular to the longitudinal axis. The profile groove forms an undercut (62) and is provided with an insertion opening (63) on the end side in the direction of its longitudinal extension. The profile projection comprises a profile web (64) and a profile head (65) formed on the profile web so as to expand the cross section. Moreover, the invention relates to an overhead conveying device with such a transport carrier system and an unloading station for automatic unloading of transport bags suspended on transport carriers.

A running rail (1) for a conveyor system, the running rail (1) having a cross-sectional profile comprising at least three interconnected profiled portions which comprise a first profiled portion (2), laterally open to the outside, for receiving first rollers (32) of a carriage (30), a second profiled portion (3), laterally open to the outside, for receiving second rollers (33) of a carriage (30), a third profiled portion (4), open in the vertical direction, for receiving third rollers (34) of a carriage (1), wherein the first (2) and the second profiled portion (3) are mirror symmetrical to a vertical central plane (40) of the running rail (1).
